- Add RAS support for RISC-V architecture - lwn. net
This series implements the RAS (Reliability, Availability and Serviceability) support for RISC-V architecture using RISC-V RERI specification It is conformant to ACPI platform error interfaces (APEI)
- Linux RISC-V IOMMU Support - LWN. net
At a high-level, the RISC-V IOMMU specification defines: 1) Memory-mapped programming interface - Mandatory and optional registers layout and description - Software guidelines for device initialization and capabilities discovery
- RISC-V: Add dynamic TSO support - LWN. net
The upcoming RISC-V Ssdtso specification introduces a bit in the senvcfg CSR to switch the memory consistency model of user mode at run-time from RVWMO to TSO The active consistency model can therefore be switched on a per-hart base and managed by the kernel on a per-process base
- RISC-V IPI Improvements - LWN. net
This series aims to improve IPI support in Linux RISC-V in following ways: 1) Treat IPIs as normal per-CPU interrupts instead of having custom RISC-V specific hooks This also makes Linux RISC-V IPI support aligned with other architectures
- Improving control-flow integrity for Linux on RISC-V - LWN. net
RISC-V is an instruction set architecture (ISA) that follows the philosophy of open-source hardware Its attractiveness lies in its lack of ISA licensing fees and that it is extensible, allowing designers to integrate custom instructions and features tailored to their specific needs
- riscv: Memory Hot(Un)Plug support - LWN. net
This series adds memory hot(un)plugging, and ZONE_DEVICE support for the RISC-V Linux port MM configuration ===== RISC-V MM has the following configuration: * Memory blocks are 128M, analogous to x86-64 It uses PMD ("hugepage") vmemmaps From that follows that 2M (PMD) worth of vmemmap spans 32768 pages á 4K which gets us 128M
- iommu riscv: Add irqbypass support - lwn. net
Platforms with implementations of the RISC-V IOMMU and AIA support directly delivering MSIs of devices assigned to guests to the VCPUs VFIO and KVM have a framework to enable such support, which is called irqbypass
- Linux RISC-V AIA Support - lwn. net
The RISC-V AIA specification is ratified as-per the RISC-V international process The latest ratified AIA specifcation can be found at: https: github com riscv riscv-aia releases download 1 0
